Many thanks for that. I think there may be both a cup problem and a
missing
dust seal. Mine is more like the one here -

But even so there are a couple of differences, ie I appear to have no
component 7, which my poor German suggests is a dust cap. Also I seem to
have two of component 10, rather than one each of 8 and 10.
I'll go out and take a couple of pics in the morning, and see what can be
sorted out.
Thanks again
